Celery: How to get the task completed time from AsyncResult

Question

I need to trace the status for the tasks. i could get the 'state', 'info' attribute from the AsyncResult obj. however, it looks there's no way to get the 'done_date'. I use MySQL as result backend so i could find the date_done column in the taskmeta table, but how could i get the task done date directly from AysncResult obj? thanks

Answer 1

You can get it from the _cache object of the AsyncResult after you have called res.result

for example

res._cache['date_done']
